MODE oF MAKING PAPER some.

SPECIFICATION forming part 'of LetteraPatent No. aezieanated. Ma a 1880.V

Application filed December 15, 1879. I

To all whom it may concern:

Be it known that I, MERRICK F. WILSON, of Chicago, in the county of Cookand State of Illinois, have invented a certain new and usefulImprovement in Mode of Making Paper Boxes, which is fully set forth inthe following specification, reference being had to the accompanyingdrawings, in which- Figure 1 represents a plan view of a paper blank cutpreviousto rolling for the construction of a series of double-neckedboxes; Fig.

2, a side elevation of a completed box, and

Fig. 3 a similar view of. the same with the covers removed and slightlyseparated from theends.

The object of my invention is to simplify and cheapen the manufacture ofwhat are known as double-necked paper boxes. These boxes have usuallybeen made heretofore from two separate pieces, the first ofwhich isformed into a cylinder, and then the second wound around it andfastencd,the latter strip being narrower than the former.

My invention consists in a process of makin g necked paper boxes,consisting in first cutting a blank with rabbets and recesses at oneside, arranged in a special manner, then winding the said blank upon amandrel to form 'a tube of two or more thicknesses with alternate 3oportions of less thickness, and then severing the tube along the centralline of the thinner portions;

It also consists in a blank cut in a peculiar form, with rabbets andrecesses of special form and arrangement extending part way across it,all of which will be herein-after fully and specifically described, andpointed out more definitely in the claims. j .j,

It also consists in the blank-itself, of peculiar form, which will behereinafter fully described.

In the drawings, A represents a blank of box-board, which is cut ofpeculiar form. On one side are recesses 00, cut out about half-wayacross the blank and at equal distances apart.

These recesses are of a width equal to twice the length of one of thenecks which it is desired to form upon the box-body when finished. Onthe same side of the blank, and at the ends thereof, strips arecut awayto form a rabbet,

(1., extending inward as'far as the recesses 00, and one-half the Widthof the latter--that is, of a width equal to that of one of the necks'onthe box-body when completed. This blank is cut from the board by asingle die at one drop,

the cutters of the die being constructed and arranged to cut out thespaces described. The blank thus formed is then wound upon a mandrel ina machine like that described in Letters Patent No.217,035, granted tome July 1, 1879, the mandrel being of such size that the entireunrecessed and unrabbeted portion of the blank will first be Wound toform a tub-e of one thickness, and then the narrow strips between therecesses and between a recess and 6 5 a rabbet will be wound around thetube first formed to form a second thickness. The ends of the blank thuswound on the mandrel are then glued, when it is evident that a papertube will be formed of double thickness, with pbr- 7o tions of but asingle thickness at regular distances from each other, and of a width.equal to the width of the cutaway portions in the blank. g

The movable cutters described in my prior patent above mentioned arearranged so that when moved up to the mandrel, they will sever the papertube along the central line of the single thickness, or, in other words,along the dotted lines in Fig. 1 of the drawings.

It is obvious that the tnbewill thus be cut into a series'of shortertubes, like that shown in Fig. 3 of the drawings, consisting of a body,B, of double thickness, provided with a short neck, b, at eachend, of asingle thickness, which is formed by the interior roll ofpaper.

The ends of the outer thickness form the usual shoulders b for thecovers 0, one of which is suitably fastened to the body of the box tomake the permanentbottom, and the 0 box is then completed, as shown inFig. 2 of the drawings.

After the tube is cut on the mandrel, so as to form separate box-bodies,these latter are slipped off from the endof the mandrel, as ex- 5plained in my aforesaid patent, and the covers fitted to the endsthereof.

By this process this particular kind of paper box may be manufacturedvery rapidly and cheaply.

2 seams The blank may be very large, so as to make a number of boxeswhen completed.

In the above-description I have specified a box of only two thicknesses,with necks of a single thickness. It is obvious, however, that bycutting the blank with special reference to the construction of a boxwith a different num-- ber of thicknesses, it may be formed with a bodyof three or even more thicknesses, and necks of a single thickness, ordouble, or even more, if desired. These modifications can be efl'ectedby simply changing the relative widths-that is to say, the dimensions inthe direction of the recessed and dotted lines in Fig. 1-of the entireand recessed portions of the blank, so as to give as many thicknesses asdesired to both the body and the necks of the box. It is also obviousthat a slight change in the cutting of the blank and in the arrangementof the cutters for severing the tube on the mandrel will make a box withbut one neck. One way of accomplishing this would be to adjust thecutters so as to sever the tube in line with one side of.the recesses,instead of on the dotted lines shown in Fig. 1, in which case therecesses should be made of a width equal to the length of a single neck,and one of the more thicknesses with alternate portions of d lessthickness, and then severing said tubealong the central line of thethinner portions, substantially as described. 1

,2. The blank A, provided on one side with narrow recesses at, extendingabout half-way across the blank, and with a rabbet, a, at each endthereof half'the width of one of the recesses and of the same depth,substantially as and for the purpose set forth.

MERRIOK WILSON.
